Replace $port & $password & $log_path as you want to.

• listen: kcptun listen port
• target: the shadowsocks address. Becasue kcptun & shadowsocks are on the same VPS. So the address is 0.0.0.0 doesn't need be changed. Unless you have mulitple IP address.
• key: make sure client & server have the same password
• crypt: make sure client & server have the same crpyt method.
• mode: make sure client & server have the same mode.

sndwnd & rcvwnd should not over the your mainum bandwidth.
How to reach the maximum bandwidth?
Increase -rcvwnd on KCP Client and -sndwnd on KCP Server simultaneously & gradually, the mininum one decides the maximum transfer rate of the link, as wnd * mtu / rtt; Then try downloading something and to see if it meets your requirements. (mtu is adjustable by -mtu)

Other parameter please check here.

$ ./server-start.sh

$ ./server-stop.sh

$ ./server-restart.sh

This script only for macOS. Other system should change the script to adjust it.
